This book collects a wealth of information about spatial audio coding into one comprehensible volume‎.‎ It is a thorough reference to the 3GPP and MPEG Parametric Stereo standards and the MPEG Surround multi‎-channel audio coding standard‎.‎ It describes key developments in coding techniques‎,‎ which is an important factor in the optimization of advanced entertainment‎,‎ communications and signal processing applications‎.‎ Until recently‎,‎ technologies for coding audio signals‎,‎ such as redundancy reduction and sophisticated source and receiver models did not incorporate spatial characteristics of source and receiving ends‎.‎ Spatial audio coding achieves much higher compression ratios than conventional coders‎.‎ It does this by representing multi‎-channel audio signals as a downmix signal plus side information that describes the perceptually‎-relevant spatial information‎.‎ Written by experts in spatial audio coding‎,‎ Spatial Audio Processing‎:‎ * reviews psychoacoustics ‎(‎the relationship between physical measures of sound and the corresponding percepts‎)‎ and spatial audio sound formats and reproduction systems‎;‎* brings together the processing‎,‎ acquisition‎,‎ mixing‎,‎ playback‎,‎ and perception of spatial audio‎,‎ with the latest coding techniques‎;‎* analyses algorithms for the efficient manipulation of multiple‎,‎ discrete and combined spatial audio channels‎,‎ including both MP3 and MPEG Surround‎;‎* shows how the same insights on source and receiver models can also be applied for manipulation of audio signals‎,‎ such as the synthesis of virtual auditory scenes employing head‎-related transfer function ‎(‎HRTF‎)‎ processing and stereo to N‎-channel audio upmix‎.‎ Audio processing research engineers and audio coding research and implementation engineers will find this an insightful guide‎.‎ Academic audio and psychoacoustic researchers‎,‎ including post‎-graduate and third/fourth year students taking courses in signal processing‎,‎ audio and speech processing‎,‎ and telecommunications‎,‎ will also benefit from the information inside‎.‎
